.5 .cop yor large mass of vwound weft.

In narrow ware shuttles commonlyl used the weft is wound on a quillwhichis rotatablysupported on a pin 'and carried in ,the bow oftheshnttle. In 'certain classes of work 1,0 it is desirable to employalargeramount of weftthan can be wound onda quilland `itis an importantobject .of my present lnvention to provide a shuttle having apreferably4 me-V tallic yarn orcop carrying casing or shell 1 5 whichissecured to a base similar `tothesupportingportions of the usualwooden` narrow Ware Shuttles.

V,Itis a further object of my'present inven- 'tion to provide a narrowware Vshuttle having' f IVJZO a cop compartment defined in part loyza`cover pivoted tothe casing and held in position by i an improved formof'readily detachable latch orhook. 'l

With these and other objects in viewwhich will appear as the descriptionproceeds, my

invention resides in the combination vand arrangement of partshereinafterdescribed and set forth in the claims. l vIn the accompanyingdrawing, wherein a ,ofconvenient embodiment of my -invention is setforth,

The pivot pin 29, as disposed in Fig. 4, is

posed with respect to the cover 2,5, so that any outward strains of saidcover will serve .to tighten thetgri-p whichthelatch has l,on the cover."l ,`his is due tothe factthatthe .latch extends fromits pivot 1in f avdirection away from thejpivt ofthe cover and, also away from thebody. l
